A convicted cop killer, now serving 25 years to life, is so sure he’ll be paroled, he placed an Internet personal ad looking for a wife, The Post has learned.

Bruce Lorick, 47, who gunned down transit Officer Joseph Keegan in 1980, placed an ad on prisonerlife.com seeking a “female between 30-57 who is unafraid of being herself, and desire[s] to be loved totally.”

His ad says he is an “emotionally secure gentleman” who is “humorous, witty, romantic, loyal, a good listener, excellent lover and a true friend.”

Lorick, an inmate at the Greenhaven Correctional Facility, was found guilty of murdering Keegan, 41, during a June 19, 1980, confrontation inside the Columbus Circle subway station.

When the officer tried to eject him for evading the fare, Lorick, then 22, turned on him.

He grabbed the cop’s gun and shot him in the head.

“I’m angry – my whole family is still angry,” said the victim’s brother, Frank Keegan, about the possibility that Lorick could be released in June.

“I want to bring out the fact that this piece of medical waste should not be released. To this day, my family is still devastated by this.”

Frank Keegan, who served 23 years as an NYPD cop before retiring from the 34th Precinct in 1978, noted that 13 members of his immediate family were city cops with a total of more than 150 years of service.

The clan, he said, is infuriated by the personal ad, in which the murderer welcomes “any Christian woman who does not consider herself a fanatic.”

“I cannot compete with God, but I can be a best friend or a husband with your help,” Lorick writes.

“I am willing to relocate upon my release.”

Keegan said he plans to personally address the parole board on Friday and will deliver the last of 2,000 signatures on a petition protesting Lorick’s release.

He also plans to present the board with a copy of Lorick’s ad, which was recently pulled from the Web site.

“This dirtbag put out on the Internet that he’s getting out and wants to marry a Christian woman – and never once did he apologize to my family,” Keegan fumed.
